Presented the programming environment that we are developing for the dam break simulation. This environment provides an easy way to program and test numerical scheme on the well-known DamBreak problem. I have presented the architecture of the framework and an example of how to program a numerical algorithm.

Presented some of the projects I have realized as an industrial application (developing technology product). Also, I presented the programming environment that I am developing for the simulation of the dam break wave;

I have presented technology transfer project (Open Channel flow simulation) in the hydro-electricity industry. I discussed the difficulties that we have faced during this project, particularly the problem of reproducing flow regime in such a complex natural environment. I have presented the result we that we have obtained and what should done to ameliorate the precision (get a better accuracy).

Technical Reports

  1. "An Extensible C++ Framework for One-Dimensional Open Channel Flow Simulation" , - J. Belanger (in preparation)

Abstract In this report we provide an introduction to ODE, then present an extensible Object-Oriented framework - written in C++ - with emphasis on the reusability of modules for ODE solvers. The ability to extend this API to accomodate new algorithms as they are developed is particularly attractive. This facilitates our work to find the best numerical method, and speed the development of a dedicated simulator for specific cases.
